man, that ain't seeds. What NFL player is going to do something like buy seeds in bulk and then put them in individual ziplocks? That's weed, and someone is a moron for having them on the sideline. Guarantee EVERY NFL locker room has weed in it somewhere, but most are smart enough to not have it on the sideline where dozens of cameras are pointed at any given moment. haha, still chuckling about this.
From what I understand, unless you have officially licensed products (including food), you have to do that to hide any product labels. So, gatorade is allowed on the sidelines, but if the player wants powerade instead, they need to be in unmarked bottles. Same for food. If David's Sunflower Seeds isn't an official NFL brand, then you gotta put them in baggies so their label isn't shown on TV.
In reality, I think theres a 0% chance that's actually weed in the baggie. But it's still hilarious.
